Tessa's Recipe Rundown...

Taste: Bursting with fresh spring flavors.
Texture: Somewhere in between a rich bread pudding and French toast!
Ease: Ridiculously easy. I think the hardest part was finding Challah at the store, which is my fave option if you can find it.
Pros: Perfect for any special breakfast or brunch.
Cons: None!
Would I make this again? Absolutely. I’ve made this countless times. Even my Aunt who doesn’t like the lemon blueberry flavor combo loved this!

Growing up, French toast was one of my absolute favorite breakfasts. My dad used to make the BEST French toast.

His secret? Extra vanilla.

I always liked my French toast with a little crispy edge and lots of maple syrup on top. I’ll take French toast over pancakes any day, though I’m realizing most people don’t agree!

So whenever there’s a special breakfast or brunch, I always make something French toast inspired.

This Lemon Blueberry French Toast Casserole is so simple and easy to make, and can be done the night before you plan on serving it. It’s absolutely perfect for Mother’s Day because of that! And I find it holds up well after baking for at least a few hours too.

The texture is really a cross between French toast and bread pudding. The exterior has a slight crunch, but the inside is ultra rich, soft, and almost like custard.

My absolute favorite bread to use for this recipe is day old Challah. It’s rich and soaks up all of the eggy goodness. If you can’t find Challah you can also use a good French or Italian loaf. OR, you can use my favorite Challah recipe with step-by-step video to make your own!

The blueberry topping on top is definitely worth the extra effort. It can be made, cooled, covered, and refrigerated for a few days. Just rewarm when ready to serve!

Lemon Blueberry French Toast Casserole can be made overnight and tastes like a combination of bread pudding and gourmet French toast. It's perfect for Mother's Day!

Ingredients

For the French toast::

  • 1 loaf (about 13 ounces) Challah, French, or Italian bread cut into cubes
  • 6 large eggs
  • 1 cup blueberries
  • 2 cups milk (any kind)
  • 1/4 cup granulated sugar
  • Zest and juice of 1 lemon
  • 1 teaspoon vanilla extract

For the sauce::

  • 1 cup granulated sugar
  • 2 tablespoons cornstarch
  • 1/4 cup fresh lemon juice
  • 1 1/2 cups blueberries

Directions

Make the French toast:

  1. Grease a 13-by-9-inch or similarly sized baking pan.
  2. Place the bread cubes in the prepared pan. In a large bowl whisk together all the remaining ingredients until very well combined. Pour half of the egg-milk mixture over the bread and stir to moisten.

  3. Top with the remaining egg-milk mixture to cover completely. Cover the pan and refrigerate for at least 2 hours or overnight.

  4. Preheat the oven to 350°F.
  5. Bake uncovered for 40 minutes, or until golden brown.

Make the sauce:

  1. While the French toast is baking, combine the sugar, cornstarch, 3/4 cup water, and the lemon juice in a small saucepan. Bring to a boil or medium heat. Add the blueberries and continue to boil, stirring often, until the syrup thickens and the blueberries begin to burst. Keep warm until ready to use.

    Can I use frozen blueberries for the sauce?

    Ohmigosh! This turned out so well! Divine. I doubled the recipe and made this in a 10 x 15 casserole dish. I also made double the sauce which really wasn’t necessary. Both were just so delicious and a huge hit at my Mother’s Day brunch. I used fresh blueberries for the casserole and frozen blueberries for the sauce. Huge organic blueberries in both cases. Worked great. Thank you!

    Not bad, had good flavour and it strue that its a cross between bread pudding and french toast. I would omit the syrup as it was really sweet with good flavor.

    I am totally missing something…..
    Place the bread cubes in the prepared pan. In a…… Pour half of the egg-milk mixture over the bread.

    Top with the remaining egg-milk mixture to cover completely. Cover and refrigerate for at least 2 hours or overnight.

    What do I do between the two halves of egg milk mixture?

    Hi Tessa!

    Your Lemmon Blueberry French Toast sound heavenly and would be a perfect accompaniment for my Easter brunch. I’m a little confused though as to if I should keep it covered when it goes in the oven or do I uncover to bake it?

    I, too, was wondering why the egg/milk mixture is added in two steps – should I stir before adding the second half? Like another commenter, was also wondering if I need to cover the dish when baking. Thanks!

    Tessa,

    Wondering why you don’t respond to viewer’s questions, yet you’ll respond to viewer’s who only have a comment? This isn’t the first time this has happened on here. It’s very disappointing as well as discouraging. I’ve ended up going to other sites to find recipes just because they are easier to understand. At the very least, the blogger will answer any and all questions, no matter how stupid they may think they are! Just a little food for thought! Have a nice day!☺

    I am with you – french toast is so much better than pancakes (my opinion). This is such a great recipe and I appreciate the video to make my own challah. What a wonderful plus! Thank you for all your great recipes and your wonderful instruction videos.
